Description

Technical Field

[0001] The utility model belongs to the technical field of bus manufacturing, and in particular relates to a steering machine fixing bracket based on a 6-meter full-load-bearing city bus. Background Art

[0002] The steering gear is the most important part of the car for steering function and an important guarantee for the driving safety of the car. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. The existing steering gear fixing bracket is made of only one special-shaped steel plate, which is cut, bent, and punched. When installing the steering gear, 4 M12 bolts, nuts and spring washers are used to fix the side of the steering gear fixing bracket of this structure. The above-mentioned steering gear fixing bracket has the following disadvantages:

[0003] 1. This structure does not take into account the impact of the torque released by the steering gear during operation on the bracket. The steering gear fixing bracket of this structure is prone to the risk of disconnection from the middle position;

[0004] 2. The steering gear fixing bracket body is made of Q235B steel plate with a thickness of 6mm. The height cross-sectional dimension of one end is significantly reduced, which increases the risk of disconnection of this structure during use. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a steering machine fixing bracket based on a 6-meter full-load-bearing city bus.

[0006] The technical solution adopted by the utility model is a steering gear fixing bracket based on a 6-meter full-load city bus, including a U-shaped side panel, a plurality of mounting holes corresponding to the steering gear are provided on the U-shaped side panel, the back side of the U-shaped side panel is connected to the steering gear through the mounting holes, and reinforcing ribs are provided on the front side.

[0007] Preferably, the reinforcing ribs are made of 6 mm thick steel plates, the inner end faces and both ends of the reinforcing ribs are welded to the U-shaped side plates, and the outer end faces do not exceed the end faces of the U-shaped side plates.

[0008] Preferably, two reinforcing ribs are provided, which are arranged respectively at the upper and lower parts of the U-shaped side plate.

[0009] Preferably, the thickness of the U-shaped side plate is 8 mm.

[0010] Compared with the prior art, the beneficial effect of the utility model is that a complete U-shaped side panel is used to install the steering gear, the cross-sectional dimensions of the side of the U-shaped side panel are complete and have no segmented surfaces, the overall structural strength of the mounting bracket is good, and two reinforcing ribs are arranged on the front of the U-shaped side panel, which well ensures the influence of the torque released by the steering gear during operation on the bracket, and prevents the steering gear fixing bracket from being disconnected during long-term operation of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the steering gear fixing bracket;

[0012] Figure 2 This is the assembly diagram of the steering gear fixing bracket. DETAILED DESCRIPTION

[0013] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0014] Example 1

[0015] like Figure 1-2 As shown, a steering gear fixing bracket based on a 6-meter full-load city bus includes a U-shaped side panel 1, which is made of a Q355B plate with a thickness of 8 mm. Four mounting holes are opened on the U-shaped side panel 1 corresponding to the steering gear. The back side of the U-shaped side panel 1 is fixedly connected to the steering gear through the mounting holes using four M12 bolts, nuts and spring washers. A reinforcing rib 2 is provided on the front side of the U-shaped side panel 1.

[0016] The above-mentioned reinforcing ribs 2 are provided with two, which are arranged respectively at the upper and lower parts of the U-shaped side panel 1. The reinforcing ribs 2 are made of a plate material Q355B with a thickness of 6 mm. The inner end face and both ends of the reinforcing ribs 2 are welded to the U-shaped side panel 1 by carbon dioxide gas shielded welding, and the outer end face of the reinforcing ribs 2 does not exceed the bent end face of the U-shaped side panel 1.

[0017] The utility model structure has the following advantages:

[0018] 1) The design structure of the steering gear fixing bracket uses a Q355B plate with a thickness of 8 mm, which is made by cutting, drilling and bending. The cross-sectional dimensions of the side where the steering gear is installed are complete and have no segmented surfaces, and the structural strength is good;

[0019] 2) The design structure assembly of the steering gear fixing bracket also uses two reinforcing ribs made of Q355B material with a thickness of 6 mm, which effectively ensures the influence of the torque released by the steering gear during operation on the bracket, and prevents the steering gear fixing bracket from being disconnected from the middle position during long-term operation of the vehicle.

[0020] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
